Problems solved by technology

[0003]Usually, because the fuel tank cannot be absolutely sealed, after a period of work, it is easy to mix granular debris into the fuel tank
When the hydraulic station is working, the particles are easy to accumulate in the precision filter, and then blockage will affect the normal operation of the hydraulic system
However, in actual processing, especially in milling and grinding, the entire system needs to run for a long time, and the oil supply failure of the hydraulic system is not allowed
[0004]In addition, due to the high-speed movement of the electric spindle, the temperature rise of the pressure lubricating oil is relatively large. At this time, the inertial force generated by the lubricating oil is also large, which leads to the delay in returning the lubricating oil The problem, which causes a large thermal error of the electric spindle

Abstract

The invention discloses an intelligent hydraulic station, which comprises a lubricating oil feeding subsystem, a cooling oil feeding subsystem, a lubricating oil return subsystem and a cooling oil return subsystem. The intelligent hydraulic station is characterized in that the lubricating oil feeding subsystem and the cooling oil feeding subsystem respectively comprise a precision filter assembly, the precision filter assemblies comprise a precise filter, two one-way valves and a differential pressure sensor, the lubricating oil return subsystem comprises a jet device, a lubricating oil return channel of an electric spindle is connected with a negative pressure chamber interface of the jet device, and oil is sprayed out through the ejection port of the jet device. Defects of failure in oil supply and non-prompt lubricating oil return in case of filter blockage in the prior art can be overcome, smoothness of pressure lubricating oil supply and return can be ensured, bubbles generated in oil return process can be removed, the real-time monitoring of the oil feeding quantity and oil return quantity of the electric spindle lubricating system can be realized, and the intelligent hydraulic station can be widely applied in lubricating oil circulation systems for electric spindles and other hydrodynamic and hydrostatic functional components.

Description

technical field [0001] The invention relates to an intelligent hydraulic station, in particular to an intelligent hydraulic system for ensuring smooth oil supply and oil return of an electric spindle or other dynamic and static pressure functional components, and capable of real-time monitoring of lubricating oil supply and oil return. Background technique [0002] In the existing dynamic and static pressure lubrication electric spindle system, it is necessary to provide lubricating oil with a certain pressure, and pump this pressure lubricating oil from the oil tank to the electric spindle lubrication channel to form a pressure-bearing oil film, and then the lubricating pressure oil returns to the main shaft through the oil return pump. At the same time, a certain pressure of cooling oil is pumped from the oil tank to the cooling channel of the electric spindle to take away the heat generated during the operation of the electric spindle in real time, through the pressure dif...
